These are the section heading, text alternative of static image and title text of URL. Three lists have been used in the actual data set, which are the top ten popular Web sites in the world, top five Web sites in The Webby Awards from the category of best navigation/ structure in year 2014, and top five Web sites in The Webby Awards from the category of best user experience in year 2014. The Web accessibility will be evaluated in terms of the error found in the Web site based on the criteria set. The list of the top five Web sites in The Webby Awards from the category of best navigation/ structure in year 2014 is identified to be having the lowest error ratio compared to the other two lists analysed, which are the top ten popular Web sites in the world and the top five websites in The Webby Awards from the category of best user experience in year 2014. The findings show that the awareness of the Web accessibility among the developers are still very low. Even the Web sites are popular or awarded, it does not mean that the Web site is fully conformed to the selected Web accessibility criteria. Although it is impossible for the Web site to achieve a full conformance on WCAG 2.0, it is still a responsibility for the Web site to look at the Web accessibility of the Web site as it will help to decrease the accessibility barriers for both normal users and disabled users.
